I hope you are starting to mend by now. Your jaw should mend well if they used surgical plates to fixate the fracture. You might also have cracked some molar teeth internally, which may not show up for some time afterwards. Symptoms: sensitive to cold and chewing fibrous foods. I had a similar crash on my DRZ when I got a screw through my knobby tyre at speed. The sudden loss of pressure made the back end swap form side to side violently. I managed to hang on from 60 mph to stationery and then topple over. Scared the crap out of me though.
